About iGAS
iGAS is caused by the Streptococcus pyogenes bacteria – also known as Group A Streptococcus.
These bacteria usually cause mild illnesses, like strep throat or impetigo (school sores).
iGAS occurs when the bacteria enter internal parts of the body – such as the blood, muscles, soft tissues or fluid around the brain. When this happens, the infection can become life-threatening.
